Small change to tiers (Patreon)

I never really went back over the benefits of each tier after I added the 2-dollar tier. And I realized that it isn't as clear on that one what you're getting.

I don't like the idea of someone giving me money and not getting the game at least a bit sooner than 'public'. Therefore, today I'll be editing the 2-dollar tier. Basically, 5-dollar and up tiers already get the game on day of release. I won't change that because I have members in each one already. The 2-dollar tier will now get the game 5 days after the upper tiers. Then public members can grab the game 2 weeks after release.
